Chemical Structure
Description
The occurrence of 2,2'-Dimethyl-[1,1'-binaphthalene]-4,4'-diamine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,2'-Dimethyl-[1,1'-binaphthalene]-4,4'-diamine (CAS 1165-03-3) is a high-purity analytical reference standard with the molecular formula C22H20N2 and a molecular weight of 312.41 g/mol.
The molecular framework of 2,2'-Dimethyl-[1,1'-binaphthalene]-4,4'-diamine (C22H20N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2,2'-Dimethyl-[1,1'-binaphthalene]-4,4'-diamine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
